Hearts winger Andrew Driver will undergo a thigh scan after suffering injury during the final stages of his recovery from knee surgery. Driver, who is yet to play for the first team this season following his summer operation, picked up the injury during a closed-doors game against St Johnstone on Tuesday.
Manager Jim Jefferies told Hearts News: "He was just pushing himself hard to get back.
"The problem is a thigh strain and is nothing to do with the previous knee injury which had kept him out.
"It has set him back a wee bit. We're getting him scanned and we'll see how he is after the international break."
